Single origin of right and left pulmonary artery branches from ascending aorta with nonbranching main pulmonary artery: Relevance to a new understanding of truncus arteriosus

Academic Article


  • We report the third known case of origin of the right and left pulmonary artery branches from the ascending aorta via a short common pulmonary artery. A large unbranching main pulmonary artery opened through a patent ductus arteriosus into the descending thoracic aorta. Preductal coarctation of the aorta and multiple congenital anomalies were also present. This rare cardiovascular malformation facilitates a new anatomic and developmental understanding of truncus arteriosus.
